A wild bender across eastern Scottish city (8)
I believe the answer is:
aberdeen
'scottish city' is the definition.
(Aberdeen is a city in Scotland)
'a wild bender across eastern' is the wordplay.
'wild' is an anagram indicator.
'across' means one lot of letters goes inside another.
'eastern' becomes 'e'.
'bender' with letters rearranged gives 'brdeen'.
'brdeen' enclosing 'e' is 'berdeen'.
'a'+'berdeen'='ABERDEEN'
(Other definitions for aberdeen that I've seen before include "football club" , "Scotland's Granite City" , "area of Scotland" , "town in Scotland" , "Scottish E. coast city" .)
